even a little workout is good, good pair of runners some shirts & tees strap on the ipod with some tunes that make you wanna move, i found that really helped, get tunes with a good pace & screw with the list in no time youll have a set or a few; do power walk easier on the joints, you can adjust stride and pace to work with song (gotta pick reasonable songs). 20 min/day 10 out 10 in.
